Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Methods A multicenter study with subjects with profound sensorineural hearing loss, who were implanted and followed up in two tertiary centers. A total of 54 ears were implanted with Cochlear™ Nucleus® CI532, 51 with Cochlear™ Nucleus® CI522 and 54 with the Cochlear™ Nucleus® CI512. Implant loss and intraoperative electrophysiological tests (electrically evoked stapedial reflex threshold \[ESRT\], neural response telemetry threshold \[T-NRT\] and impedance), postoperative data (C-level, T-level, dynamic range, T-NRT and power consumption) and intracochlear position of the active electrode were analyzed with Nucleus Custom Sound 4.4 software.
